Functions

func AnySideEffects

func AnySideEffects(n ir.Node) bool

AnySideEffects reports whether n contains any operations that could have observable side effects.

func StaticLoc

func StaticLoc(n ir.Node) (name *ir.Name, offset int64, ok bool)

StaticLoc returns the static address of n, if n has one, or else nil.

func StaticName

func StaticName(t *types.Type) *ir.Name

StaticName returns a name backed by a (writable) static data symbol. Use readonlystaticname for read-only node.

Types

type Entry

type Entry struct {
	Xoffset int64   // struct, array only
	Expr    ir.Node // bytes of run-time computed expressions
}

type Plan

type Plan struct {
	E []Entry
}

type Schedule

type Schedule struct {
	// Out is the ordered list of dynamic initialization
	// statements.
	Out []ir.Node

	Plans map[ir.Node]*Plan
	Temps map[ir.Node]*ir.Name
}

An Schedule is used to decompose assignment statements into static and dynamic initialization parts. Static initializations are handled by populating variables' linker symbol data, while dynamic initializations are accumulated to be executed in order.

func (*Schedule) StaticAssign

func (s *Schedule) StaticAssign(l *ir.Name, loff int64, r ir.Node, typ *types.Type) bool

func (*Schedule) StaticInit

func (s *Schedule) StaticInit(n ir.Node)

StaticInit adds an initialization statement n to the schedule.
